Viruses, bacteria, all kinds of Invaders with its own DNA have been a part of nature for a long time. If the body could not deal with that we would not be around. Every once in awhile I’m sure a particular DNA bit comes along that messes everything up but I’m not real worried . I expect such bits of bad luck to be rare.
So why are they acting like they are over this one that is not even a big deal.
DNA is not RNA. RNA reprograms cells.
